Our History in Whitehall, PA

In 1992, Charles Terry Kozo started the company in Whitehall, Pennsylvania. His vision was to create an auto repair business that focused on engine and transmission replacement. The goal was to provide a high degree of customer satisfaction, with cars and trucks that ran better and stayed on the road longer.

Stephen Lang, Jr. joined Auto Motors of Lehigh Valley in 1994. He brought expertise in diagnostics and general auto repair gained through his years working at Lang’s Gulf. When Stephen purchased Auto Motors of Lehigh Valley in 2011, his son, Derek J. Lang, joined the company, taking over management of the office in 2012.

In 2017, Derek bought Auto Motors of Lehigh Valley and incorporated another business, Diamond Automotive. Not only does Derek continue the commitment to quality engine and transmission repair, but he has expanded the general maintenance and repair capabilities of our auto repair shop with seven bays and four full-time technicians.
